Good evening all,
Turns out that we CAN post a document using Google Documents as the storage site. We can thank Bryan Shader for the following steps:
1. Go to Google Documents -- you could log into your Google account and then click on Docs
2. Upload a file -- select the Upload tab at the upper left jut under the words Google Docs
3. Share the file with yourself -- you'll have to list yourself with a non-Google email address in the text box that appears, and then click on Invite Viewers
4. An email will be sent to you with a link to the PDF file
5. Place this link in the blog.
